GUIDE-SHIELD FOR TYPE-WRITING MACHINES.-

SPECIFICATION forming part of Letters Patent No. 493,503, dated March14, 1893.

Application filed June 9, 1892. Serial No. 436,105. (No model.)

To aZZ whom it may concern:

Be itknown that I, REBECOA E. HOOPER, a citizen of the United States,residing at San Francisco, in the county of San Francisco and State ofCalifornia, have invented certain new and usefullmprovements inGuide-Shields for Type-Writing Machines; and I do hereby declare thefollowing to be a full, clear, and exact description of saidinvention,such as will enable others skilled in the art to which it mostnearly appertains to make, use, and practice the same.

The present invention relates to a certain new and useful device which Iterm guide shield for type writing machines, and the same consists inthe arrangement of parts and details as will be hereinafter more fullyset forth in the drawings, described and pointed out in thespecification.

It is well known that much trouble and an noyance is caused users oftypewriters inorder to address envelopes, 850., in such a manner as toproduce an unblurred letter, unless the free end of envelope be heldfirmly against the carriage roll, and at the same time great difficultyis experienced in placing between the rolls paper sheets when it isdejsi red to secure a number of manifold copies at the same time.

The object of my invention is to provide a simple and effective guideshield, which will permit of ready attachment to the carriage roll,which shield is formed with projecting lugs or fingers adapted to form aguide way within which envelope or ends of sheet may be held in order toinsure proper guidance between the carriage rolls, and at the same timehold the paper firmly against the surface of large carriage roll, thusobviating liability of type blurring or smudging paper when broughtthereagainst.

Referring to the drawings forming a part of this application, whereinsimilar letters of reference are used to denote corresponding partsthroughout entire specification and several views-Figure l is aperspective view of guide shield applied to carriage roll. Fig. 2 is anend elevation of a portion of a typewriter showing the shield inposition. Fig. 3

is a detail perspective View of the shield, and Fig. 4. is a similarview showing a modification.

The letter A, is used to indicate the carriage roll of type writer, andA", the smaller pressure roll located behind same. For the purpose ofpresent illustration I have shown my device appliedv to carriage roll ofwhat is known as the Remington machine, although it will be understoodthat same maybe readily attached to any of the well known type writers.My guide shield is represented by letter B, and is constructed of springelastic material. The shape of the shield conforms to the surface of thecarriage roll, consequently when applied closely adheres thereto, owingto its elastic quality, consequently the shield grips surface of roll A.Projecting forwardly from the top of guide shield are the curved arms,lips, or lugs O, which form a guide passage 0', within which end ofenvelope D, is held. These arms, lugs, lips, or fingers may be madeintegral with the shield or separate therefrom and secured thereto inany well known manner.

While I prefer to provide the shield of .spring elastic material andpermit of same adhering of itself direct to surface of carriage roll, itis obvious that same may consist of a narrow longitudinal strip havingholding flange or arms projecting therefrom, and spring clips beprovidedforthe purpose of securingguide piece to roll'of carriage, asshown in Fig. 4:.

When it is desired to address envelopes,the guide shield is secured tocarriage roll, and end or top of sheet, 850., to be addressed is placedwithin guide passage formed by projecting arm, flange, lip, or lug. Asthe roll is rotated the shield is carried thereby until envelope is inproper position to be addressed. It will be noticed that top thereofwill be held by guide shield, and the bottom by pressure roll A, asusual, thus causing surface or back of same to firmly bear upon face ofcarriage roll, thus giving a solid surface for writing on. If only thebottom of the envelope were held, and the top thereof free from contactwith carriage roll, a loose surface would be presented to be addressed,which would give to pressure of the type, and consequently cause ablurred impression.

This device will be found of great importance when desired to insert anumber of sheets in typewriter at the same time. It is a ditficultmatter to properly place same between surface of pressure and carriageroll without causing some of the sheets to crawl, thus causingtype-writer line to run at an angle. By my device an even feed betweenthe rolls is insured without creating delays of carefully adjusting thesheets. After carriage rolls make one complete rotation guide shield maybe removed by simply exerting sufficient pressure thereon as will besufficitlelnt to overcome hold thereof upon carriage ro Having thusdescribed my invention, what I claim as new, and desire to secure byLetters Patent of the United States, is

1. A guide shield for type writers adapted to be mounted on the carriageroll and having a projecting flange or arm whereby a passage way isformed in which the end of the sheet may be held.

2. A guide shield for typewriters constructed of spring elasticmaterial, and provided with guide passage, said shield adapted to besecured to carriage roll by its own elasticity.

3. The combination with carriage roll of a typewriter, of a springelastic guide shield adapted to be secured directly thereto, and of theholding flange for maintaining writing material in proper position.

4. The combination with carriage roll of a typewriter, of a springelastic guide shield, said shield conforming in shape to surface of rolland adapted to be held thereon by its own elasticity, and of the holdingflange or arm secured thereto.

7 In testimony whereofI affix my signature in presence of two witnesses.
